Animal origin protein is getting less and less so plant origin protein becomes the main source of animal nutrition. The exogenous protease has played a major part in helping to release plant origin protein nitrogen, which are trapped within insoluble fibers cell walls, and radically improve the efficiency of meat production. The beneficial effects documented are beyond doubt, but the responses obtained are variable and sometimes lacking. Therefore the study was to investigate the effects of dietary electrolyte balance (dEB) value in fully plant origin low protein diets supplemented with exogenous protease on the growth performance of broiler under high ambient temperatures. 800 Arbor Acres broiler were randomly allocated to five 5 feeding treatments of four replicates. There were 40 birds kept in a 3.8 M2 floor feeding pen of which ambient temperature was between 28~32 ℃. In 1-3 weeks feeds contained 21% CP, and 19% for 4-5 weeks, energy level are the same for the two stages (3200 Kcal/kg feed). Treatment 1: control group (calculated 225 meq Na+, K+, Cl-/kg), Treatment 2: adding water electrolyte (calculated 50 meq/L, water:feed ratio=2 L/kg), Treatment 3: dietary exogenous protease (1,000 U/kg feed), Treatment 4: dietary electrolyte (calculated 325 meq/kg), Treatment 5: dietary exogenous protease and electrolyte. The results showed that the 5th week body weight (P = 0.004), overall body weight gain (P = 0.004) and feed intake (P<0.001) were increased significantly between treatments. By using protease to improve dietary protein digestibility or increase dEB value could improve growth performance, it also has the results of addition and multiplication of these two methods.
